For the first time since the 1980s, all nine nuclear-armed states are expanding their arsenals at once. Our new Quarterly Nuclear Memo by Manpreet Sethi and @hreepsamudra.bsky.social maps a quarter where worrying developments clearly outnumbered stabilising ones. a thread🧵
In alignment with APLN's 2026–2030 Research Strategy, the APLN Quarterly Nuclear Memo tracks, analyses and summarises nuclear developments shaping the Asia-Pacific security environment.
Developments are classified according to four analytical categories: 

1. Disruptive (developments posing acute or immediate risks to the nuclear order and regional stability);
2. Stabilising (steps that reduce risk or build confidence);
3. Worrisome (trends that, if unchecked, could worsen the nuclear order); and
4. Dialogue-based (activities that involve two or more interlocutors).
